I started preparing around the beginning of Sept but really didn't get too focused on preparing until late October. In total I spent about 90 hours. In hind site I likely could have gotten away with much less preparation time but i had been hearing the exam was really tough and it turns out the questions in the simulators (I used WhizLabs) are more difficult than the ones on the actual exam in many cases.
